Description

technical field [0001] The invention belongs to the technical field of power transmission, and in particular relates to a transmission device or equipment using gears and hydraulic transmission. Background technique [0002] The traditional car power transmission is that the engine outputs power to the gearbox through the power output shaft or flywheel disc, and then the gearbox decelerates the output power to drive the drive shaft to make the vehicle move forward or backward. In highway maintenance construction, sometimes the maintenance construction process requires the engine of the special vehicle for highway maintenance to provide a stable low-speed working condition. At a low speed of about km / h, the forward speed of the maintenance vehicle is in an unstable state. At this time, the engine of the vehicle is running in the low-speed area, and the power output is not in the best state, so that the equipment of the special vehicle for road maintenance cannot be provided d...

Problems solved by technology

In highway maintenance construction, sometimes the maintenance construction process requires the engine of the special vehicle for highway maintenance to provide a stable low-speed working condition. At a low speed of about km / h, the forward speed of the maintenance vehicle is in an unstable state. At this time, the engine of the vehicle is running in the low-speed area, and the power output is not in the best state, so that the equipment of the special vehicle for road maintenance cannot be provided during construction work. required motivation

The traditional technical solution adopted to solve this technical problem is to add an auxiliary engine to the road maintenance special vehicle to provide low-speed forward power for the road maintenance special vehicle, which increases the manufacturing cost of the road maintenance special vehicle and requires a certain amount of time.
